Really? Software sold in a box, can't resell it? Tell me more.
Not excusing either party, just pointing out it's not that uncommon in high-end corporate software.
You're not buying a thing in a box, you're buying a license with associated terms. Which may include prohibiting resale.
If the US had credible anti-trust laws this kind of thing would be taken apart in court. But it doesn't, so here we are.
